Amongst the many problems I have been meaning to sort out, I got round to looking at the rear window (Touring) opening today.

Rear window (you know how they open independently to the tail-gate on Touring) has not been working.

Checked the micro-switch (shorted it out) and still no actuator activity.

I took the lock apart and the actuator [67 11 1 392 020] off.

I plugged the actuator into the wiring for where the tail-gate lock actuator is (looks the same, but diff p/n) and I get some sort of response out of it - like it is trying to operate, but in the wrong direction. So looking like the actuator might be working, but not getting a signal.

What do I check for on the actuator wiring to see if the actuator is getting a signal? If it's not the micro-switch, what else could be wrong if I'm getting no signal?

Is there any way I can properly test the actuator independently from the vehicle (without destroying it!)?

Thanks

Matt.
